LOUIS ANTOINE GRINDA Y GUIOL, OF SAN GERVASIO, BARCELONA, SPAIN;

DEVICE FOR PREVENTING DERAILING OF TRAINS.

SPECIFICATION forming part of Letters Patent No. 658,174, dated September 18, 1900.

Application filed April 10,1900.

T0 on whom it may concern:

Be it known that 1, Louis ANTOINE GRINDA Y GUIoL, gentleman, a citizen of Spain, residing at 18 Berna, San Gervasio, Barcelona, in the Kingdom of Spain, have invented certain new and useful Improvements in Devices for Preventing the Derailing of Trains, of which the following is a clear description.

This invention relates to a novel device for preventing the derailing of trains.

The invention consists in the improved device for preventing the derailing of trains and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter pointed out, and finally embodied in the clauses of the claim.

A form of this invention is illustrated in the accompanying drawings, in which- Figure 1 is a view of the guide in elevation, with a transverse section of the railway-track and supplementary rail. Fig. 2 is a vertical section of the guide on the line A B in Fig. 1. Fig. 3 is a horizontal section on the line C D in Fig. 1.

The guide I), fixed to the frame of the locomotive, consists of a fork-shaped piece of forged iron or other suitable material, the two arms of which are turned toward the ground and fit loosely, so as to admit of play to the supplementary rail, which is fixed between the two ordinary rails of the track and which stands higher than said rails. (See Fig. 1.) In order to prevent as far as possible the objectionable friction which might arise between the guide b and the rail a, a roller 0 is arranged between the arms of the guide and runs on the upper part of the head of the rail. The head of the supplementary rail fits in the groove of the roller 0. load dition to the roller 0 smaller rollers'd d are arranged horizontally and vertically on the lower ends of the armsof the guide. These rollers bear respectively on the under surface of the head of the rail a and on its web. The shafts of the rollers 0, cl, and d are introduced through openings formed in the arms of the guide 17. These openings are lined with tubes f e e, and each tube is furnished With.a projection or feather which prevents it from turning, and they may be retained in their places by means of set-screws. These tubes serve as Serial No- 12,S09. (No model.)

bearings for the shafts of the rollers. The rollers are constantly lubricated by means of a box It for the roller 0 and the boxes '9 for the rollers d d, the lubricating material (grease or oil) being conveyed to the lubricating-boxes by means of tubes t' and j.

The guides b may be arranged in any suitable position on the locomotive or on the carriages; but it is preferable to place one in front of the locomotive and another at the back thereof, one being placed in the middle of each carriage and another at the end.

As derailing occurs chiefly Where a line or track is curved or inclined the supplementary rail should be principally fitted in such places; but it is desirable that it should be employed over the whole extent of the track. The supplementary rail is fixed on the sleepers in the same manner as the ordinary rails.

The guide I) and the rail a may be varied in any suitable manner without departing from the spirit of the invention.

Having now particularly described and ascertained the nature'of my said'invention and in what manner the same is to be performed, I declare that what I claim is- 1. In a device for preventing the derailing of cars or other vehicles, the combination of a rail adapted to be disposed under the vehicle, a forked guide adapted to be carried by said vehicle and receiving the rail,a roller journaled in said guide above the rail and adaptedto bear upon the tread portion thereof, said roller having a peripheral groove receiving said tread portion of the rail, other rollers also journaled in said guide opposite, and adapted to bear against, portions of said rail subjacent the tread portion thereof, and tubular blocks removably arranged in said guide and affording bearings for said rollers, substantially as described.

2. In a device for preventing the derailing of cars or other vehicles, the combination of a rail adapted to be disposed under the vehicle, a forked guide adapted to be carried by said vehicle and receiving the rail, a roller ,7

journaled in said guide above the rail and adapted to bear upon the tread portion thereof, said roller having a peripheral groove receiving said tread portion of the rail, other rollers also journaled in said guide opposite,

and adapted to bear against, portions-of said I specification in thep'resenee of two subscribrail subjaoent thetreadportion thereofytu ing witnesses.
